ABSTRACT

The aspects of the present disclosure provide a method and an apparatus for implementing hardware resource allocation. For example, the apparatus includes processing circuitry. The processing circuitry obtains a first value that is indicative of an allocable resource quantity of a hardware resource in a computing device. The processing circuitry also receives a second value that is indicative of a requested resource quantity of the hardware resource by a user, and then determines whether the second value is greater than the first value. When the second value is determined to be less than or equal to the first value, the processing circuitry requests the computing device to allocate the hardware resource of the requested resource quantity to the user, and subtracts the second value from the first value to update the allocable resource quantity of the hardware resource in the computing device.

No. 16/284,455, filed Feb. 25, 2019, which is a continuation of International Application No. PCT/CN2017/112254, filed on Nov. 22, 2017, which claims priority to Chinese Patent Application No. 201611146923.3, entitled “METHOD AND APPARATUS FOR IMPLEMENTING HARDWARE RESOURCE ALLOCATION” filed with the Patent Office of China on Dec. 13, 2016. The entire disclosures of the prior applications are hereby incorporated by reference in their entirety.

FIELD OF THE TECHNOLOGY

The present disclosure relates to the field of the Internet, and specifically to a method and an apparatus for implementing hardware resource allocation, and a storage medium.

BACKGROUND OF THE DISCLOSURE

Resources of a computing device may be divided into a computing resource and a storage resource, where the computing resource such as a CPU (Central Processing Unit) or a memory is mainly used for computing, and the storage resource is mainly used to read/write data, and may be undertaken by a magnetic disk. With advancements in hardware technologies, a computing resource and a storage resource of a single computing device become increasingly large, and moreover a unit cost also becomes increasingly low. With hardware performance improvement of a single computing device, to make full use of a hardware capability of the computing device, a plurality of application programs may be deployed in the computing device. For example, a plurality of database applications is deployed into one computing device, so as to reduce a use cost of a single database application.

In a cloud technology, particularly, in a virtualized environment, a hardware resource in a computing device is usually subleased to different users for use by means of an application program, and these users to which the application program is subleased may be referred to as tenants. A plurality of application programs is deployed in one computing device. In this way, a hardware resource of the one computing device is leased by a plurality of tenants. Currently, a plurality of tenants uses a hardware resource of a computing device in a manner of allocation and scheduling based on an operating system, and a preemption-based hardware resource allocation and use policy is usually used. That is, a busy application program may preempt the hardware resource of the computing device and use the hardware resource for computing and storage of the busy application program. However, in this scenario, an idle application program cannot obtain the hardware resource used for computing and storage, and a processing capability of the idle application program is greatly reduced. In a fair multi-tenant environment, the hardware resource allocation manner in the related technology is unfair to a tenant of the idle application program.

SUMMARY

In view of this, aspects of the present disclosure provide a method and an apparatus for implementing hardware resource allocation, and a non-transitory computer-readable storage medium, so as to resolve a technical problem in the related technology that hardware resource allocation performed in a preemption-based manner causes a processing capability of an idle application program to be reduced.

In some examples, the apparatus includes processing circuitry. The processing circuitry obtains a first value that is indicative of an allocable resource quantity of a hardware resource in a computing device. The processing circuitry also receives a second value that is indicative of a requested resource quantity of the hardware resource by a user, and then determines whether the second value is less than or equal to the first value. When the second value is determined to be less than or equal to the first value, the processing circuitry requests the computing device to allocate the hardware resource of the requested resource quantity to the user, and subtracts the second value from the first value to update the allocable resource quantity of the hardware resource in the computing device.

According to an aspect of the disclosure, the processing circuitry selects the computing device from a first computing device and a second computing device that are available for hardware resource allocation. Then the processing circuitry compares the second value with the first value of the selected computing device. When the second value is determined to be greater than the first value, the processing circuitry selects the other of the first computing device and the second computing device for the hardware resource allocation.

In some embodiments, the processing circuitry obtains the first value that is indicative of the allocable resource quantity of at least one of a disk space and a memory space in the computing device.

In some embodiments, the processing circuitry receives the second value that is indicative of the requested resource quantity of the hardware resource for a database application.

In some embodiments, when the computing device is implemented in the apparatus, the processing circuitry allocates the hardware resource of the requested resource quantity to the user; when the computing device is separate from the apparatus, the processing circuitry sends a resource allocation request including the second value to the computing device via interface circuitry.

In some embodiments, the processing circuitry initializes the first value as a function of a maximum resource quantity of the computing device and an amount of resource quantity used by an operating system in the computing device.

Aspects of the disclosure also provide a non-transitory computer-readable medium storing instructions which when executed by a computer cause the computer to perform the method for implementing hardware resource allocation.

It can be seen from above that, the embodiments of the present disclosure have the following beneficial effects:

In the embodiments of the present disclosure, an allocable resource quantity of a computing device is determined, a requested resource quantity that is input by a user is received, and when the requested resource quantity is not greater than the allocable resource quantity of the computing device, a hardware resource of the requested resource quantity is allocated to a user to establish an application program; and moreover, the allocable resource quantity of the computing device minus the requested resource quantity is used as an updated allocable resource quantity, thereby controlling and limiting use and preemption of a single application program on a hardware resource of the computing device, to avoid occurrence of a scenario in which a busy application program preempts an idle application program.

DESCRIPTION OF EMBODIMENTS

In order to make the foregoing objectives, features, and advantages of the present disclosure more comprehensible, the present disclosure is further described in detail in the following through specific embodiments with reference to the accompanying drawings.

In the related technology, a plurality of application programs is deployed in a single computing device, and an application program uses a hardware resource of the computing device by means of allocation and scheduling based on an operating system. For example, a busy database application may preempt a hardware resource of a computing device and use the hardware resource for computing and storage of the busy database application. However, in this scenario, an idle database application cannot obtain computing and storage resources, and a processing capability of the idle database application is greatly reduced, where a database application may include a database and a database instance, and the database instance may be understood as a processing program used to operate the database. Moreover, currently a computing device is usually allowed to be used by a plurality of tenants simultaneously, and a tenant is a user that uses a hardware resource of the computing device. In a fair multi-tenant environment, the hardware resource allocation manner in the related technology is unfair to a tenant of the idle application program. To this end, the embodiments of the present disclosure provide a method and an apparatus for implementing hardware resource allocation, to resolve unfavorable impact of resource preemption on an idle tenant, allocate a hardware resource to each tenant, and control the hardware resource used by each tenant without reducing resource use of an idle application program while ensuring that a busy application program uses a hardware resource.

Referring to FIG. 1, FIG. 1 shows a schematic diagram of an application scenario according to an embodiment of the present disclosure. The method for implementing hardware resource allocation provided in this embodiment of the present disclosure is described from the perspective of an apparatus for implementing hardware resource allocation, and the apparatus for implementing hardware resource allocation may be specifically loaded in a computing device (e.g., a computer) or a server. In a case, when there is one computing device, the apparatus for implementing hardware resource allocation provided in this embodiment of the present disclosure may be directly loaded in the computing device or loaded in a server, to allocate a hardware resource of the computing device. In another case, when there is a plurality of computing devices, the apparatus for implementing hardware resource allocation provided in this embodiment of the present disclosure may be loaded in a computing device or loaded in a server, to allocate a hardware resource of the computing device. Methods for implementing hardware resource allocation in the two different cases are separately described below.

Referring to FIG. 2, FIG. 2 shows an embodiment of a method for implementing hardware resource allocation according to an embodiment of the present disclosure. The method for implementing hardware resource allocation may be applied to a server, and the method for implementing hardware resource allocation may include the following steps:

Step 201. Obtain a maximum allocable resource quantity of a first computing device and determine the maximum allocable resource quantity as an allocable resource quantity of the first computing device when the first computing device does not perform hardware resource allocation.

In this embodiment, when there is one computing device, that is, there is the first computing device, a hardware resource of the first computing device needs to be allocated. The maximum allocable resource quantity of the first computing device is first obtained. In some possible implementations of the present disclosure, the maximum allocable resource quantity may include a maximum allocable disk space and a maximum allocable memory space. The maximum allocable disk space is equal to a maximum disk space minus an operating-system occupied disk space, and the maximum allocable memory space is equal to a maximum memory space minus an operating-system occupied memory space. That is, the maximum allocable disk space of the first computing device is equal to the maximum disk space of the first computing device minus the operating-system occupied disk space in the first computing device, and the maximum allocable memory space of the first computing device is equal to the maximum memory space of the first computing device minus the operating-system occupied memory space in the first device. When the first computing device does not perform hardware resource allocation, that is, in an initial status, the maximum allocable resource quantity of the first computing device may be determined as the allocable resource quantity of the first computing device. In some possible implementations of the present disclosure, the allocable resource quantity may include an allocable disk space and an allocable memory space. That is, when the first computing device does not perform hardware resource allocation, the maximum allocable disk space of the first computing device is determined as the allocable disk space of the first computing device, and the maximum allocable memory space of the first computing device is determined as the allocable memory space of the first computing device. In an embodiment, step 201 may be understood as a preparation step before performing the method for implementing hardware resource allocation provided in this embodiment of the present disclosure.

If parameters are used for indication, the maximum disk space may be indicated by using SMAX, the maximum memory space may be indicated by using MMAX, the operating-system occupied disk space may be indicated by using OSS, the operating-system occupied memory space may be indicated by using OSM, the maximum allocable disk space may be indicated by using DSMAX, and the maximum allocable memory space may be indicated by using DMMAX, the foregoing relationship may be indicated as:

DSMAX=SMAX−OSS; and DMMAX=MMAX−OSM.

If the allocable disk space may be indicated by using DDS, and the allocable memory space may be indicated by using DDM, it can be known that DDM<=DMMAX, and DDS<=DSMAX.

Step 202. Receive a requested resource quantity that is input by a user.

When the user needs to request to use a resource in the computing device, a requested resource quantity may be input to a client of the user. In some possible implementations of the present disclosure, the requested resource quantity may include a requested disk space and a requested memory space. For example, the user inputs a requested disk space of 100 G and a requested memory space of 10 G to establish a database application.

A requested resource quantity of a disk space may be indicated by using SDER, and a requested resource quantity of a memory space may be indicated by using MDER.

Step 203. Judge whether the requested resource quantity is greater than an allocable resource quantity of a selected computing device, the selected computing device being the first computing device.

In this embodiment, there is one first computing device. In this case, the selected computing device is the first computing device. After the requested resource quantity that is input by the user is received, whether the requested resource quantity is greater than the allocable resource quantity of the selected computing device needs to be judged. In some possible implementations of the present disclosure, judging whether the requested resource quantity is greater than the allocable resource quantity of the selected computing device may be judging whether the requested disk space is greater than the allocable disk space and whether the requested memory space is greater than the allocable memory space. If the requested resource quantity is greater than the allocable resource quantity of the selected computing device, that is, the requested disk space is greater than the allocable disk space or the requested memory space is greater than the allocable memory space, hardware resource allocation cannot be completed, and prompt information may be sent to the user; or if the requested resource quantity is not greater than the allocable resource quantity of the selected computing device, that is, the requested disk space is not greater than the allocable disk space and the requested memory space is not greater than the allocable memory space, subsequent steps of performing hardware resource allocation of the first computing device may be performed.

Step 204. Send, if the requested resource quantity is not greater than the allocable resource quantity of the selected computing device, a resource allocation request including the requested resource quantity to the selected computing device, so that the selected computing device allocates a hardware resource of the requested resource quantity to the user.

The selected computing device may allocate the hardware resource of the requested resource quantity to the user to establish an application program instance, and a maximum usable resource quantity of the application program instance is not greater than the requested resource quantity. For example, a maximum usable memory of the application program instance is MDER, and a disk capacity is SDER.

When it is judged that the requested resource quantity is not greater than the allocable resource quantity of the selected computing device, the resource allocation request including the requested resource quantity is sent to the first computing device. If the apparatus for implementing hardware resource allocation provided in this embodiment of the present disclosure is directly loaded in the first computing device, the resource allocation request may be sent inside the first computing device; or if the apparatus for implementing hardware resource allocation provided in this embodiment of the present disclosure is directly loaded in the server, the resource allocation request may be sent from the server to the first computing device. In this embodiment, after receiving the resource allocation request, the first computing device may allocate the hardware resource of the requested resource quantity to the user. Specifically, the first computing device may allocate the hardware resource of the size of the requested disk space and the size of the requested memory space to the user sending the requested resource quantity. In some possible implementations of the present disclosure, the selected computing device may be specifically configured to allocate the hardware resource of the requested resource quantity to the user to establish a database application. In this embodiment, the selected computing device may be the first computing device.

Step 205. Determine a result of the allocable resource quantity of the selected computing device minus the requested resource quantity as an allocable resource quantity of the selected computing device.

After the selected computing device performs hardware resource allocation, the allocable resource quantity of the selected computing device needs to be updated, and a result of the original allocable resource quantity minus the requested resource quantity is an updated allocable resource quantity. In some possible implementations of the present disclosure, a result of the allocable disk space of the selected computing device minus the requested disk space may be determined as the allocable disk space of the selected computing device, and a result of the allocable memory space of the selected computing device minus the requested memory space may be determined as the allocable memory space of the selected computing device. In this embodiment, the selected computing device may be the first computing device.

In this way, in this embodiment of the present disclosure, an allocable resource quantity of a computing device is determined, a requested resource quantity that is input by a user is received, and when the requested resource quantity is not greater than the allocable resource quantity of the computing device, a hardware resource of the requested resource quantity is allocated to a user to establish an application program; and moreover, the allocable resource quantity of the computing device minus the requested resource quantity is used as an updated allocable resource quantity, thereby controlling and limiting use and preemption of a single application program on a hardware resource of the computing device, to avoid occurrence of a scenario in which a busy application program preempts an idle application program.

Based on the foregoing embodiment, a case in which there is a plurality of computing devices further exists, that is, in addition to the first computing device, one or more second computing devices may further exist. When the user needs to request to use a resource in a computing device, one of the first computing device and the second computing device may be selected to allocate a hardware resource of the computing device to the user. Therefore, in some possible implementations of the present disclosure, the method may further include: obtaining a maximum allocable resource quantity of a second computing device and determining the maximum allocable resource quantity as an allocable resource quantity of the second computing device when the second computing device does not perform hardware resource allocation; selecting, after the receiving a requested resource quantity that is input by a user and before the judging whether the requested resource quantity is greater than an allocable resource quantity of a selected computing device, one of the first computing device and the second computing device as a selected computing device; judging, if the requested resource quantity is greater than the allocable resource quantity of the selected computing device, whether both of the first computing device and the second computing device are selected; and reselecting, if not both of the first computing device and the second computing device are selected, one of the first computing device and the second computing device as a selected computing device. Referring to FIG. 3, FIG. 3 shows an embodiment of a method for implementing hardware resource allocation according to an embodiment of the present disclosure. The method may be applied to a server, and this embodiment may include the following steps:

Step 301. Obtain a maximum allocable resource quantity of a first computing device and determine the maximum allocable resource quantity as an allocable resource quantity of the first computing device when the first computing device does not perform hardware resource allocation.

Step 302. Obtain a maximum allocable resource quantity of a second computing device and determine the maximum allocable resource quantity as an allocable resource quantity of the second computing device when the second computing device does not perform hardware resource allocation.

Similarly, in some possible implementations of the present disclosure, the maximum allocable resource quantity may include a maximum allocable disk space and a maximum allocable memory space. The maximum allocable disk space is equal to a maximum disk space minus an operating-system occupied disk space, and the maximum allocable memory space is equal to a maximum memory space minus an operating-system occupied memory space. That is, the maximum allocable disk space of the second computing device is equal to the maximum disk space of the second computing device minus the operating-system occupied disk space in the second computing device, and the maximum allocable memory space of the second computing device is equal to the maximum memory space of the second computing device minus the operating-system occupied memory space in the second computing device. When the second computing device does not perform hardware resource allocation, that is, in an initial status, the maximum allocable resource quantity of the second computing device may be determined as the allocable resource quantity of the second computing device. In some possible implementations of the present disclosure, the allocable resource quantity may include an allocable disk space and an allocable memory space. That is, when the second computing device does not perform hardware resource allocation, the maximum allocable disk space of the second computing device is determined as the allocable disk space of the second computing device, and the maximum allocable memory space of the second computing device is determined as the allocable memory space of the second computing device.

In an embodiment, step 301 and step 302 may be both understood as preparation steps before performing the method for implementing hardware resource allocation provided in this embodiment of the present disclosure.

Step 303. Receive a requested resource quantity that is input by a user.

In some possible implementations of the present disclosure, the requested resource quantity may include a requested disk space and a requested memory space.

Step 304. Select one of the first computing device and the second computing device as a selected computing device.

In actual application, one of the first computing device and the second computing device may be randomly selected as the selected computing device, or one of the first computing device and the second computing device may be selected as the selected computing device according to an order such as an identifier order.

Step 305. Judge whether the requested resource quantity is greater than an allocable resource quantity of a selected computing device, and if yes, enter step 306, or if no, enter step 307.

Step 306. Judge whether both of the first computing device and the second computing device are selected, and if yes, end, or if no, return to step 304.

If the requested resource quantity is greater than the allocable resource quantity of the selected computing device, that is, the requested disk space is greater than the allocable disk space of the selected computing device or the requested memory space is greater than the allocable memory space of the selected computing device, the selected computing device cannot complete hardware resource allocation, and another computing device needs to be selected. Before a selected computing device is reselected, whether both of the first computing device and the second computing device are selected is first judged. If no, return to reselect one of the first computing device and the second computing device as a selected computing device. If both of the first computing device and the second computing device are selected, there is currently no computing device that may satisfy the requested resource quantity, and the hardware resource allocation process ends.

Step 307. Send a resource allocation request including the requested resource quantity to the selected computing device, so that the selected computing device allocates a hardware resource of the requested resource quantity to the user.

When it is judged that the requested resource quantity is not greater than the allocable resource quantity of the selected computing device, that is, the requested disk space is not greater than the allocable disk space of the selected computing device and the requested memory space is not greater than the allocable memory space of the selected computing device, the resource allocation request including the requested resource quantity may be sent to the selected computing device. After receiving the resource allocation request, the selected computing device may allocate the hardware resource of the requested resource quantity to the user. Specifically, the selected computing device may allocate the hardware resource of the size of the requested disk space and the size of the requested memory space to the user sending the requested resource quantity. In some possible implementations of the present disclosure, the selected computing device may be specifically configured to allocate the hardware resource of the requested resource quantity to the user to establish a database application.

Step 308. Determine a result of the allocable resource quantity of the selected computing device minus the requested resource quantity as an allocable resource quantity of the selected computing device.

After the selected computing device performs hardware resource allocation, the allocable resource quantity of the selected computing device needs to be updated, and a result of the original allocable resource quantity minus the requested resource quantity is an updated allocable resource quantity. In some possible implementations of the present disclosure, a result of the allocable disk space of the selected computing device minus the requested disk space may be determined as the allocable disk space of the selected computing device, and a result of the allocable memory space of the selected computing device minus the requested memory space may be determined as the allocable memory space of the selected computing device.

In this way, in this embodiment of the present disclosure, an allocable resource quantity of a plurality of computing devices is determined, one computing device is selected from the plurality of computing devices, a requested resource quantity that is input by a user is received, and when the requested resource quantity is not greater than the allocable resource quantity of the computing device, a hardware resource of the requested resource quantity is allocated to a user to establish an application program; and moreover, the allocable resource quantity of the computing device minus the requested resource quantity is used as an updated allocable resource quantity, thereby allocating the hardware resource among the plurality of computing devices, and controlling and limiting use and preemption of a single application program on a hardware resource of the computing device, to avoid occurrence of a scenario in which a busy application program preempts an idle application program.

Based on the foregoing embodiment of the method for implementing hardware resource allocation, in some possible implementations of the present disclosure, before the selecting one of the first computing device and the second computing device as a selected computing device, the method may further include: judging whether the requested resource quantity is greater than the maximum allocable resource quantity of the first computing device and the maximum allocable resource quantity of the second computing device; and selecting, if the requested resource quantity is not greater than the maximum allocable resource quantity of the first computing device and the maximum allocable resource quantity of the second computing device, one of the first computing device and the second computing device as a selected computing device. Referring to FIG. 4, FIG. 4 shows an embodiment of a method for implementing hardware resource allocation according to an embodiment of the present disclosure. The method may be applied to a server, and this embodiment may include the following steps:

Step 401. Obtain a maximum allocable resource quantity of a first computing device and determine the maximum allocable resource quantity as an allocable resource quantity of the first computing device when the first computing device does not perform hardware resource allocation.

Step 402. Obtain a maximum allocable resource quantity of a second computing device and determine the maximum allocable resource quantity as an allocable resource quantity of the second computing device when the second computing device does not perform hardware resource allocation.

Step 403. Receive a requested resource quantity that is input by a user.

Step 404. Judge whether the requested resource quantity is greater than the maximum allocable resource quantity of the first computing device and the maximum allocable resource quantity of the second computing device, and if yes, end, or if no, enter step 405.

After the requested resource quantity that is input by the user is received, whether the requested resource quantity is greater than the maximum allocable resource quantity of the first computing device and the maximum allocable resource quantity of the second computing device is first judged. If the requested resource quantity is greater than the maximum allocable resource quantity of each computing device, hardware resource allocation cannot be performed, computing device selection does not need to be performed, and the hardware resource allocation process directly ends, so as to save a resource and consumed time for performing hardware resource allocation. Specifically, this step may be implemented by judging whether the requested disk space is greater than the allocable disk space of the first computing device and the allocable disk space of the second computing device and whether the requested memory space is greater than the allocable memory space of the first computing device and the allocable memory space of the second computing device, and if the requested disk space is greater than the allocable disk space of the first computing device and the allocable disk space of the second computing device and the requested memory space is greater than the allocable memory space of the first computing device and the allocable memory space of the second computing device, directly end, or if the requested disk space is not greater than the allocable disk space of the first computing device and the allocable disk space of the second computing device or the requested memory space is not greater than the allocable memory space of the first computing device and the allocable memory space of the second computing device, enter step 405.

Step 405. Select one of the first computing device and the second computing device as a selected computing device.

Step 406. Judge whether the requested resource quantity is greater than an allocable resource quantity of a selected computing device, and if yes, enter step 407, or if no, enter step 408.

Step 407. Judge whether both of the first computing device and the second computing device are selected, and if yes, end, or if no, return to step 405.

Step 408. Send a resource allocation request including the requested resource quantity to the selected computing device, so that the selected computing device allocates a hardware resource of the requested resource quantity to the user.

Step 409. Determine a result of the allocable resource quantity of the selected computing device minus the requested resource quantity as an allocable resource quantity of the selected computing device.

In this embodiment, other steps than step 404 are similar to those in the foregoing embodiment. For corresponding description, refer to the foregoing embodiment. Details are not described herein again.
